The following data show the cooling temperatures of a freshly brewed cup of coffee after it is poured from the brewing pot into a serving cup. The brewing pot temperature is approximately 180 F.

Time (min) 0 5 8 11 15 18 22 25 30 34 38 42 45 50
Temp (F) 185.1 160.1 167.9 145.2 142.8 138.3 126.2 114.5 118.1 118.5 112.9 113.8 94.9 100.5

The output for an exponential model ln(Temp) = 0 + 1Time + , t is below.
